Setting The Record Straight

Till this day, the overwhelming majority of India’s citizens are ill-informed about the legal status of the State of Jammu & Kashmir (inclusive of PoK), i.e. whether it is legally a part of India or whether it is disputed territory. If asked, they tend to ASSUME that it is disputed territory. However, a careful reading of the UN Security Council Resolution 47 (1948) submitted jointly by the Representatives for Belgium, Canada, Republic of China, Colombia, the United Kingdom and United States of America and adopted by the Security Council at its 286th meeting held on April 21, 1948 (Document No. 5/726, dated the 21st April, 1948), followed by a detailed account of how the Ceasefire Agreement was negotiated and finally inked on July 28, 1949, all prove beyond any reasonable doubt that it is Pakistan that has consistently shied away from implementing the UNSC’s Reolution 47.
Reproduced below is the first-hand detailed account of the entire negotiating process and the benchmarks that were used for drafting the temporary ceasefire agreement. This should, once and for all, clear any doubts that anyone harbours about the legal status of undivided Jammu & Kashmir.

Updates On Pakistan's Air-Defence Artillery Force Modernisation Efforts

Pakistan being a national security/garrison state will obviously not want to share the critical operating parameters of its weapon systems, especially those pertaining to air-defence, even with its own citizens. Nor will the citizens dare reveal anything for fear of being labelled as traitors or being abducted and subjected to torture or even fatal decapitation by its state security agencies. Therefore, to spare such retards from such miseries, I am revealing below all the relevant information concerning the Pakistan Army’s CPMIEC-supplied FM-90 SHORADS (handed over on March 16, 2016), the LY-80E MR-SAM (handed over on March 12, 2017), and the FN-16 VSHORADS that will in the near future replace the Pakistan Army’s existing QW-1/QW-2 (shamelessly renamed as Anza Mk.1/Anza Mk.2) MANPADS. The contents of this thread will also hopefully benefit all war-planners of India’s armed forces. Bhaarat Maa Zindabaad! India Paindabaad!     
All three armed services of Pakistan are presently engaged in replacing legacy air-defence systems and sensors of US and European origin with China-supplied products. For instance, the YLC-2V High Guard 3-D S-Band high-power radars have replaced the PAF’s older FPS-89/100 radars at Sakesar, Badin, Skardu and Gilgit, while the Army’s 1980s vintage 68 SIEMENS-built SILLACS L-Band MPDR-45 (with 45km-range), MPDR-60 (with 60km-range) and MPDR-90 (with 90km-range) and now being replaced by the NORINCO-supplied CS-RB1 HGR-106 medium-power 210km-range gapfiller radars.
This will then leave the PAF with only four Northrop Grumman TPS- 63s and six Lockheed Martin TPS-77s for peacetime monitoring of the country’s air-defence identification zone.
Now being delivered are CEIEC-supplied JY-27A 280km-range VHF radars and related TS-504 multi-point troposcatter communications relay systems that will be used by the Army’s three CPMIEC-supplied LY-80E medium-range surface-to-air missile regiments and the three CPMIEC-supplied FM-90 SHORADS regiments.
In addition, the Pakistan Navy’s three Marine Battalions have inducted into service the CS-RB1 HGR-106 radars, along with NORINCO-supplied 6.8-tonne PG-99 35mm towed anti-aircraft guns and Sichuan Military Electronics Industries Group Company (SEMIC)’s Type 825 fire-control radars.
The PG-99, a re-engineered Oerlikon-Contraves GDF of early 1980s vintage, is gas-operated and comes with a rate of fire of up to 1,100 rounds/minute, and the muzzle velocity is up to 1,175 metres/second, together with high aiming speed, low recoil force and small dispersion. Its engagement range is 4km. The PG-99 is mounted on a cradle which is designed to carry guns and the mobile platform. It contains the hydro-mechanical recoil mechanism, which absorbs the recoil forces. 
The lower part of the cradle comprises the two-axle chassis and the outriggers with the leveling spindles for four-point support in the firing positions. Raising and lowering the levelling spindles and raising the wheels are done electro-hydraulically, or manually in the case of power failure. The gun can be traversed 360 degree and its elevation/depression angles are +92 degree/-5 degree.
The Type 825 fire-control system can acquire targets at a range of up to 40km, track them at a maximum distance of 32km, and identify them at ranges of up to 6km.

Arjun Mk.2 MBT Now A Firm Reality

Contrary to widespread speculation, the Indian Army (IA) has not forsaken or given up on the Arjun Mk.2 main battle tank (MBT). Instead, for the past four years, the IA’s Directorate General of Mechanised Warfare has been overseeing a collective developmental effort involving the DRDO, and the MoD-owned defence public-sector undertakings and private-sector OEMs that will in the near future result in a fully-loaded 60-tonne MBT armed with a 120mm smoothbore cannon while retaining the existing 1,400hp powerpack.
Under the supervision and guidance of the DRDO’s Avadi-based Combat Vehicles Research & Development Establishment (CVRDE), and with the help of the MoD’s Directorate General of Quality Assurance (DGQA) and the IA’s Corps of Electronics & Mechanical Engineers (EME), a number of key decisions have been to achieve a weight reduction of 8 tonnes in the existing design of the 68-tonne Arjun Mk.1A MBTs, 118 of which are now in delivery. 
For starters, the baseline hull of the Arjun Mk.2 will no longer be built with imported low-carbon, nickel-chromium-molybdenum rolled homogeneous armor (RHA) steel, but with lighter high-nitrogen steel (HNS) whose production technology has been mastered by the DRDO’s Hyderabad-based Defence Metallurgical Research Laboratory (DMRL) and has been transferred to Jindal Stainless Steel Ltd (Hisar). HNS will also be used by TATA Motors Ltd for producing the 83 Kestrel 8 x 8 armoured personnel carriers already on order.   
HNS is produced in a four-step process: primary melting of the steel can carried out in either induction furnace or electric arc furnace by using appropriate raw materials; secondary melting can be carryout in by nitrogen gas-purging in to the metal; under ladle refining, ferro-nitrates are added to molten metal for obtaining final nitrogen content in the alloy if it is required and hot-rolling is carried out in a single heat, without reheating. Minimum percentage of reduction should not be less than 75% of the slab thickness. To be placed in strategic locations in both the hull and turret will be the DRDO-developed ‘Kanchan’ ceramics-based composite laminate armour tiles as well as indigenously-built explosive reactive armour (ERA) tiles developed by the DRDO’s High Energy Materials Research Laboratory (HEMRL) on the front and sides of the hull and turret sections.
To ensure optimal weight budgeting during the production engineering stage, the CVRDE has contracted Dynamatic Technologies Ltd, which specialises in complex, five-axis robotic machining, as well as in converting two-dimension paper blueprints into three-dimension computer model that are more precise, and have tighter tolerances. Digitising the drawings creates a baseline configuration for greater accuracy. This in turn streamlines manufacturing, since conventional manufacturing based on two-dimensional paper blueprints tend to leave tiny gaps between the different components of an assembly that were filled with shims, leading to increased weight. But by digitising blueprints, those tiny gaps can be entirely eliminated during the manufacturing process.
Under another weight-reduction exercise, the CVRDE has contracted the Alicon Group for building all-aluminium road-wheels and ventilators for not only the Arjun Mk.2, but also for the IA’s existing upgraded T-72CIA medium tanks. They will replace the all-steel road-wheels built by Sundaram Industries for the Arjun Mk.1A. Similarly, TATA Power SED has been contracted for producing all-electric turret stabilisation/traverse systems, in place of the existing electro-hydraulic system.  
Improvements have also been made to the 1,400hp powerpack (comprising the MTU 838 Ka-501 diesel engine and RENK’s RK-304S gearbox) through the usage of indigenously developed cooling systems.
However, the area that will see the Arjun Mk.2 emerging as a true new-generation MBT will be vectronics, and in particular the battlespace management system (BMS), which has been designed to operate at the unit-level and below, and which will synthesise the battlespace situational awareness picture for the unit commander, whether it be a mechanised infan­try regiment or an armoured regiment. The MBT and selected infan­trymen will thus become situational awareness platforms. 
This project, which was started only in 2008, has since been pushed at a faster rate as this constitutes the cutting edge of the IA’s theatre-level Command Information Decision Support System (CIDSS) programme that is being run by IA HQ’s Directorate of Information Systems. The Future Infantry Soldier as a System (F-INSAS), which is also a part of the CIDSS project, is being progressed by the IA HQ’s Directorate of Infantry but will be a part of the overall BMS and battlespace surveillance system (BSS) network of the IA.
The BSS and BMS are in turn being integrated by IA HQ’s Directorate of Signals with other components of the fourth-generation Tactical Command, Control, Communications and Information (TAC-C3I) system through the CIDSS channel. Through the BMS and BSS the IA wants to provide a Divisional-level command-and-control system spanning the entire tactical battle area (TBA) spreading across individuals, detachments, combat platforms, sensors, sub-units, units to the Brigade Commander/Regimental Commander; achieve faster reaction capability and flexibility in command and control by providing information automatically in the right place at the right time, thereby compressing the OODA loop; provide a strong foundation for making decisions based on near-real time situational awareness and battlespace transparency, providing consistent and well-structured information, thereby enhancing the information handling capability of commanders at all levels; and strengthening information exchange by having a strong messaging and replication mechanism.
The BMS will be a highly mobile and integrated system with high data transmission rates, comprising a tactical hand-held computer with individual soldiers, tactical computers at Battle Group HQ, and armoured vehicles employing application/database servers connected via a data-enabled TAC-C3I communications network, all of which generate a common operational picture of the TBA. The software-defined radio-based communications nets will optimally utilise the bandwidth available for military communications, and will not interfere with the legacy communications hardware. They will be fitted to MBTs, ICVs and APCs and will be scalable to ensure their availability to all elements ranging from man-portable SDRs to high-power SDRs for armoured vehicles.
The original proposed time-lines for implementation of the BMS and BSS were as follows:
Phase-1: Integration of the system, establishment of the testbed lab and field-trials at testbed locations (one Combat Group and three Infantry Battalion Groups) by 2012. However, this timeline was subsequently stalled for two years due to indecision in the delimitation between the BMS and the F-INSAS.
Phase-2: Equipping of all armoured and mechanised infantry formations commencing in 2017.
Phase-3: Upgradation of the system by 2022.
Both the BMS and F-INSAS will make use of a host of digitised GIS-based tools (pertaining to both friendly and enemy territories) that are now available (work on them began in 2009) for the IA’s South-Western, Western and Northern Command HQs and that can be readily uploaded on to any armoured vehicle’s autonomous land navigation system (ALNS) and BMS terminal. Military Geospatial Information System (MGIS) helps in generating terrain trafficability maps, commonly referred to as Going Maps (GM), when data pertaining to five thematic layers, viz., soil, slope, moisture, land use, and landform is fed into the system. It is then integrated to produce the GMs in a three-level hierarchical manner. Terrain Feature Extraction System (TFES) is used for extracting terrain parameters or themes (land-use/land cover, landform, and soil type) from satellite images and associated knowledge base in an automated mode. The land use, landform, and soil layer has 10, 28, and 12 classifications, respectively. For land-use classification, a multi-layer perceptron (MLP) is used for training and subsequent generation of corresponding themes. The landform classification uses a texture-based method for creating a database that is used for training MLP. Terrain Reasoner System (TRS) helps decision-makers (troop commanders, wargamers and mission planners) in a combat development setting for arriving at route alternatives that are largely determined by the threat capability of the obstacles and strategic nature of the regions to be negotiated for a pre-specified mission accomplishment risk factor (MARF). The problem of navigation and route planning of vehicles or troops is defined as the final behavioural outcome of a sequence of complex decisions involving several criteria that are often conflicting and difficult to model. A fuzzy inference system has been built to implement the perceive-reason-act decision cycle of a moving agent representing a vehicle or a foot soldier in a safety-critical tactically driven scenario. Terrain Matching System (TMS) is an intelligent decision-support system based on the integration of CBR and fuzzy multi-criteria decision-making.
The F-INSAS project will be implemented in three phases—Phase-1 includes weapons, body armour, clothing and individual equipment; Phase-2 is the target acquisition system and Phase-3 comprises the computer sub-system, SDR sub-system, and operating software integration. Since the Directorate of Infantry has been developing Phase-3 of F-INSAS on its own, rather than being part of the BMS project, this has amounted to re-inventing the wheel. Instead, what should have been done was to develop Phase-3 of F-INSAS as part of the overall BMS developmental effort.
